6. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks
Abstract : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. READ MORE

7. Numerical study of flows related to aerated stirred tanks
Abstract : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. READ MORE

8. Flow and turbulence in the discharge stream of different agitators for stirred tanks
Abstract : In this thesis, the fluid dynamic properties of the conventional Rushton turbine and another impeller type, the Scaba Radial flow Gas dispersing Turbine (with six concave blades) are compared. For comparison, point-wise velocity measurements were made in the discharge of the two turbine types using Hot-Wire Anemometry in constant temperature mode (CTA) with a split film probe. READ MORE

10. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems
Abstract : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. READ MORE
